How to edit details in form 49 a ?

Hi,
I have applied for pan card online, form 49 A. Now I have to send it a hard copy of form 49 A to IT department.But while sending filled 49 A I came to know that name to be printed on card is wrong spelled, I want to edit my filled form 49 A, but not getting any thing,

All the link having content for edit pan card data if already pan number is allotted, but in my case pan number is not allotted and I only want to edit form 49 A before sending it IT department.

Please assist.
Thanks
